USB: serial: quatech2: fix sleep-while-atomic in close

The write URB was being killed using the synchronous interface while
holding a spin lock in close().

Simply drop the lock and busy-flag update, something which would have
been taken care of by the completion handler if the URB was in flight.

Fixes: f7a33e608d9a ("USB: serial: add quatech2 usb to serial driver")
